The nearest tenth, is the number that follows the decimal point. In this case, there is no decimal point.
However, if you meant the nearest tens:
look at the place value to the right (ones). The number inside is a 5. Because it is a 5, and 5 and greater you round up, round up.
2767545 rounded to the nearest tens is 2767550.
